Title: Charged-particle source
Inventor: HOSOKI SHIGEYUKI
IPC: H01J37/08
Filed: 1981-05-22
Abstract: PURPOSE: To obtain a charged-particle source which functions as an electrostatic- discharge cathode (an electron source) when a relatively negative electric potential is applied to electrodes each having opposed pointed ends, and functions as a field- ionizing-type ion source when a relatively positive electric potential is applied to the said electrodes.  
     CONSTITUTION: A charged-particle generating chamber 34, other than the openings of a first and a second electrode 11 and 12, is isolated in a vacuum condition of the device body. In carrying out electrostatic discharge, a vacuum pressure similar to the conventional pressure can be obtained by using an exhasut pump 25 which realizes an extra-high vacuum, such as an ion pump. A focusing lens system for electrons or ions can be achieved with the first and the second electrodes 11 and 12. A focusing lens 24 constitutes a pole piece, which is used as an electromagnetic lens also working as a magnetic path, by maens of electrodes 18 and 20. Here, when a non-magnetic electrode 19 is added, the electrodes 18, 19, 20 constitute an electrostatic single lens, which is called an Einzer lens. In using ion beams, ion beams are focused on the surface of a sample 13 by setting on a power source 15' by means of switches 38, 39, and 16, and giving an electric field reducing the speed of ions to the electrode 19 by means of the power source 15'. Owing to such arrangement mentioned above, the focusing abilities for electrons and ions of the device can be increased.

Title: Three-wheel type unmanned vehicle
Inventor: TABATA HIDEMITSU
IPC: B61B13/00
Filed: 1990-03-28
Abstract: PURPOSE:To enable travel without rattling even on a hurdle floor and enable steering with little body oscillation by forming the respective wheels of a three- wheel type battery-driven unmanned vehicle into the same diameter, and deciding the front wheel and one of the rear wheels to be steering-driving wheels and one other wheel to be a steered wheel. CONSTITUTION:In a three-wheel type battery-driven unmanned vehicle, a steered wheel 33 has the same wheel diameter as steering-driving wheels 31, 32, and is steering-controlled by a drive mechanism ST. The driving motors of the steering-driving wheels 31, 32 are driven by a drive mechanism to perform the travel of the vehicle. At the time of changing the direction, the respective steering angles of the steering motors M2 of the steering-driving wheels 31, 32 and steered wheel 33 are controlled to perform steering. Because of the steering-driving wheel 31, 32 and steered wheel 33 having the same wheel diameter, rattling is sufficiently small even if the floor is in the grating shape, and therefore the vertical vibration of a truck 10 is hardly generated.

Filed: 1979-06-18
Abstract: PURPOSE:To protect the output transistor from the breakdown at the short-circuit time of the load, by giving the short circuit to the base current of the control transistor via the diode and thus turning off the output transistor. CONSTITUTION:Output transistor (TR)14 has the ON/OFF action, and the base current of TR14 is controlled by control TR11. Then diode 13 is connected between the collector of TR14 and the base of TR11. Thus the short circuit is given to the base current of TR11 via diode 13 when load 15 has the short circuit. As a result, TR11 and then TR14 are turned off. In this way, the output TR can be prevented from the breakdown at the time of the short circuit fault.

Title: Stress measuring method
Inventor: OTA HIROYUKI
IPC: G01L1/00
Filed: 1990-03-28
Abstract: PURPOSE:To make it possible to measure the stress distribution of a sample to be measured having steps highly accurately by receiving the reflected light from the sample to be measured, and controlling a sample stage or a lens so that the stage or the lens is moved and the focal point is aligned by using the received light. CONSTITUTION:When laser light which is projected on a sample 13 is not focused on the surface of the sample, the reflected light from the surface of the sample is not focused at the position of a pinhole plate 8. The light reaching a photodetector becomes less. At this time, a micromotion stage 14 is moved with respect to an objective lens 15. The stage is controlled with a beam-spot- diameter controller 12 so that the amount of the light inputted into the photodetector 9 becomes the maximum value. At this time, the lens 15 can be controlled and moved so as to obtain focusing. The amount of movement (Z) of the stage 14 or the lens 15 is inputted into a computer 11 from the controller 12. The position coordinates (X and Y) in the plane in plane scanning of the stage 14 are further inputted into the computer 11. Thus, the coordinate values at the Raman spectrum measuring point in the sample 13 can be recognized with the computer 11.
